IMPORTANT NOTICE (Regarding first fire up):
When the unit is turned on for
the first time, it should be turned onto high without the fan on for the first 4
hours. This will cure the paint, logs, gasket material and other products used in
the manufacturing process. It is advisable to open a window or door, as the unit
will start to smoke and can irritate some people. After the unit has gone through
the first burn, turn the unit off, let the unit get cold then remove the glass door
and clean it with a good gas fireplace glass cleaner, available at your local ENVIRO
dealer. See “
